Jetty pool connection configuration error mysql: javax.naming.NameNotFoundException; remaining name is' env / jdbc / --- (mysql 5.0 + jetty 7.0.1)

Question

My configuration files

Project / WEB-INF / web.xml:

<resource-ref>
    <description>ConnectionPool DataSource Reference</description>
    <res-ref-name>jdbc/mysql</res-ref-name>
    <res-type>javax.sql.DataSource</res-type>
    <res-auth>Container</res-auth>
</resource-ref>

Project / WEB-INF / Berth-env.xml:

<New id="mysql" class="org.eclipse.jetty.plus.jndi.Resource">
    <Arg></Arg>
<Arg>jdbc/mysql</Arg>
    <Arg>
        <New class="org.apache.commons.dbcp.BasicDataSource">
            <Set name="driverClassName">com.mysql.jdbc.Driver</Set>
            <Set name="url">jdbc:mysql://localhost:3306/db</Set>
            <Set name="username">user</Set>
            <Set name="password">pwd</Set>
            <Set name="maxActive">50</Set>
        </New>
    </Arg>
</New>

code to call:

ctx = new InitialContext();
ds = (DataSource) ctx.lookup("java:comp/env/jdbc/mysql");
con=ds.getConnection();

---

scripts to launch the berth:

java -DOPTIONS=plus -jar start.jar

java -jar start.jar

In any case, to start the berth, I received the following error:

---

javax.naming.NameNotFoundException; remaining name 'env/jdbc/mysql'
        at org.eclipse.jetty.jndi.NamingContext.lookup(NamingContext.java:632)
        at org.eclipse.jetty.jndi.NamingContext.lookup(NamingContext.java:663)

        at org.eclipse.jetty.jndi.java.javaRootURLContext.lookup(javaRootURLContext.java:110)
        at javax.naming.InitialContext.lookup(Unknown Source)

Questions:

• What is the problem?
• Any other configurations needed?
• where to put the following jar files:
  • Common-DBHP-1.2.2.jar
  • Mysql-socket-java-5.1.10-bin.jar

Thanks!

Answer 1

Note. It is assumed that you are using Jetty 7.2.2+ (it may work with any Jetty 7.0 +).

, . , Jetty webapp, Jetty, jetty-env.xml webapp. , jetty.xml( ${JETTY_INSTALL_DIR}/etc:

, Jetty JNDI, jetty-web.xml.

Answer 4

The Jetty documentation points to a three-step process for using a JNDI resource, such as a database. These instructions should apply to Jetty 7 and Jetty 8.

• Edit the file $JETTY_HOME/start.inias follows:

• Change the server OPTIONSto include a plus, for example:

  OPTIONS=Server,jsp,jmx,resources,websocket,ext,plus

• At the bottom of the file, in the "Configuration Files" section, add the following line after etc/jetty.xml:

  etc/jetty-plus.xml
